Based on the electroosmotic reinforcement mechanism of pulsating direct current (PDC) with a high energy efficiency ratio, the calculation method of PDC electroosmosis drainage rate was verified under different potential gradients using two forms of voltage loading, i.e., constant direct current (CDC) and PDC. The drainage weight and electric current were achieved by laboratory tests, and then the energy efficiency ratio, soil resistivity and contact resistance was calculated. The energy consumption of each test group was analyzed by considering the initial potential gradient. The obtained results show that under the same potential gradient, the difference in soil resistivity and electroosmotic drainage between PDC and CDC is not significant, but there is a significant difference in contact resistance, which leads to low current intensity and high energy efficiency ratio in the PDC test group. The expression of the electroosmotic drainage rate of the PDC is described with the coefficient μ, and then the energy efficiency ratio versus potential gradient curve is calculated, which is in good agreement with the experimental results. The reason for the lower energy consumption of PDC electroosmosis compared to CDC is described in terms of the drainage mechanism of electroosmosis.

基于高能效比的脉动直流电（PDC）电渗强化机理，采用恒直流电（CDC）和恒定直流电（CDC）两种电压加载形式，验证了不同电位梯度下PDC电渗排水率的计算方法。 PDC。通过实验室测试获得排水重量和电流，然后计算能效比、土壤电阻率和接触电阻。通过考虑初始电位梯度来分析每个测试组的能量消耗。结果表明，在相同电位梯度下，PDC和CDC的土壤电阻率和电渗排水差异并不显着，但接触电阻存在显着差异，导致PDC和CDC的电流强度较低，能效比较高。 PDC测试组。用系数μ描述PDC的电渗排水率，进而计算出能效比与电势梯度曲线，与实验结果吻合较好。从电渗排水机理方面描述了PDC电渗比CDC能耗低的原因。
